Natural Gas Grill Quick Connect Hose question
I recently purchased a new home and have purchased a NG grill that came with a gray plastic\rubber extension hose and a quick connect coupling. When I connected the grill I found that the shut off valve for the grill line was left on by the previous owner while the quick connect end was just closed while no appliance was connected. My question is do I need to disconnect the hose after each time I use the grill or is it ok to leave connected for the whole season? Also the hose is in direct sunlight at times during the day. Does this pose any danger since it has gas in it?
